Dear R-Users, I think I have encountered a potential bug (or at least unwanted behavior), but I'm not sure so I wanted to post here first. Lately I've been encountering an error when running a package I put together. I have my package set up to check for updates when it loads but this error occurs and stops the package from loading:
Error : .onLoad failed in loadNamespace() for 'rNMR', details: call: read.dcf(file = tmpf) error: Line starting '<SCRIPT language=Jav ...' is malformed! Error: package/namespace load failed for 'rNMR' I tracked to the following line of code from my package: available.packages(contrib.url(repos = "http://rnmr.nmrfam.wisc.edu/R/";, type = "win.binary")) I dug a little deeper and found the following line of code from available.packages() to be causing the problem: z <- tryCatch(download.file(url = paste(repos, "PACKAGES.gz", sep = "/"), destfile = tmpf, method = method, cacheOK = FALSE, quiet = TRUE, mode = "wb"), error = identity) The problem occurs because "PACKAGES.gz" does not exist in the repository, so my router redirects the invalid URL to a search page and some JavaScript is downloaded instead. The error is generated when R tries to read the downloaded file: res0 <- read.dcf(file = tmpf) Error in read.dcf(file = tmpf) : Line starting '<SCRIPT language=Jav ...' is malformed! The repository does have a "PACKAGES" file, but it never gets read because download.file() does not generate an error. I've fixed the issue by uploading a "PACKAGES.gz" file to the repository, but I wanted to point out the issue in case anybody else has encountered this problem. This problem may be unique to my particular system configuration, in which case a fix may not be justified. Otherwise, it may be a good idea to check for a "PACKAGES" file in the repository if an error is encountered when trying to read the downloaded "PACKAGES.gz" file.
